Johann Rafelski

Professor Johann Rafelski is a distinguished theoretical physicist at the University of Arizona's Department of Physics within the College of Science. With over 37 years of service at the university, he holds additional appointments in the Applied Mathematics Program and Theoretical Astrophysics Program, and is tenured in the Arizona Research Laboratory. His academic journey includes professorships at the University of Frankfurt and University of Cape Town, along with significant research positions at CERN, Argonne National Laboratory, and the University of Pennsylvania.

Rafelski's research focuses on the quantum vacuum structure, behavior of matter under extreme conditions, and quark-gluon plasma. His work explores how energy transforms into matter and antimatter, particularly through strangeness production, and applies laboratory insights to early universe processes. He investigates radiation effects from strong acceleration, including those generated by ultra-intense laser pulses, and participates in pulsed laser fusion research. His scholarly contributions include two influential textbooks: Relativity Matters (2017) and Modern Special Relativity (2022), which connect historical developments with current research frontiers.

Analysis of his recent publications reveals a sustained focus on quark-gluon plasma physics, cosmic evolution, strong field quantum electrodynamics, and innovative fusion approaches. His work increasingly integrates cosmological perspectives with laboratory-scale physics, particularly examining how primordial conditions inform contemporary high-energy experiments. The recurring themes across his recent articles demonstrate a cohesive research program bridging particle physics, cosmology, and quantum field theory under extreme conditions.

• Elected Fellow, American Physical Society (2013)
• Elected to Faculty Senate University of Arizona (2018-2022)
• Named Fulbright Fellow (Summers 2019-2021)
• Elected member of Academia Europea (2021)

Professor Rafelski has mentored 15 graduate students since 2000 and served as principal investigator for international programs strengthening US research ties with Brazil, Germany, and Poland. He founded the international conference series on Strangeness in Quark Matter and remains active in related committees. With 45 years of sustained involvement with CERN, where he continues as a guest scientist, he has built extensive international collaborations. His research has been supported by various grants enabling his exploration of quantum vacuum phenomena, quark-gluon plasma, and applications to cosmology and fusion energy. The establishment of his YouTube channel 'Creation of Matter' demonstrates his commitment to science communication and education.
